There's not much "sonic" innovation. Most sounds I think think I could get if I got myself on some basic synths or VSTs in twenty minutes.
There's not many notes on "policeman" or many of the other tunes. That fucking pisses me off when there's not discernible musical notes.
Drums are all over the place, pointless.
Cogent structure? Not really. There's nothing strong on these things that keeps them together. It is simply a number of unrelated synth layers on top of each other. That repetitive key line on "not too good" is a bit shit, although the author defnitely likes it. Maybe because it approximates a TUNE?!
Dynamics? Come on, some loud or quiet bits would be nice. Something resembling an overall texture. Some kind of character, otherwise it tends to just be disengaged noise.

"Time Taken" is probably the best tune. Some of the metallic synth sounds are nice.

For this kind of stuff, I have found piling on loads and loads of layers is a very good thing, maybe add some kindly reverb as well. With only a few layers, these kind of things sound very very sparse and typically very dull.
